LIFTER DESIGN MACHINE.

Application filed May 7,

This invention relates to means for producing a design in a web ofpaper. This design may be produced by preferably wetting the paper andlongitudinally corrugat- 5 ing it by means of a pair of annularlygrooved rolls. one of which is lifted at intervals in order to produce adesign in the paper web.

In the drawings Figure 1' represents a plan view and Fig. 2 a sectionalview of the machine taken 011 the line 2-2 of Fig. 1.

10 and 11 show the frame of the machine, suitably tied by braces 12, 12.13 shows the roll of paper, from which it passes over the 15 guide roll14, and under rolls 15 and 16. and into thetank 17 where the paper iswetted. The wet web of paper 18 then passes upon the cylinder 19 whichis annularly corrugated at 20. The paper then passes around 20 thecorrugated cylinder 19 and under the small annularly corrugated roll 24.The cylinder 19 is mounted. on a shaft 25. and driven by gear 26, andoperated by means of a pulley 27 or by any other suitable means;

The small roll 24 is mounted upon the shaft 29 and is driven by gear 30meshing into gear 26. i

In order to produce the desired design which is shown in the Web ofpaper at 32, 30 the roll 24 must be lifted away from cylindcr 19 atintervals. This is accomplished by means of a cam 33, operating a lever34 that may be provided with a roller engaging the cam This lever 34 ispivoted at 35 35 and the other end of the lever supports the shaft 29,to which the small corrugated roll is connected. The lever 34 issupported in a bracket 36 which is fastened to frame of the stituted.

machine. This bracket 361's provided with two upwardlyextending parts37, 38, in which the shaft 35 is pivoted. This bracket is also providedwith a projecting portion 40 which supports the cam shaft 41. Thecamshaft 4.1 is driven by means of a gear 42, which engages the cylindergear 26. The near end of the cam shaftis provided with a spline 43. anda nut 44. screwed, in order that the cam 33 may be removed from theshaft, and another cam having ditterent projections. may replace it.This cam may be provided with as many projections as is desired forlifting the small This nut may be un:

corrugated roll at intervals desired, which may be regular or irregular.The lever 34 is pressed downwardly by means of a spring 45. r y

Thecorrugated roll 24. may be removed from lever 34 and from the arm 46,by removing caps 17 and a newroll may be sub- The new roll may beprovided with cut away portions; if desiredto produce modifications ot'the design.

Various modifications may be introduced in the construction of thismachine without departing from the spirit of the invention.

l'claiin as my invention:

In a machine for producing designs in paper webs and in combination, apair of anuularlv grooved rolls between which the paper web is passedwhereby the web is longitudinally corrugated, a cam to separate therolls at intervals to thereby provide alternate corrugated and plainportions in the web. and means to rotate the rolls and the cam.
